I just bought a used Annie 64 Match singl shot, and when trying to zero the scope I mounted, I discovered the bolt wouldn't stay cocked. After closing the bolt, and locking the bolt handle down, the rear of the bolt is forward, in the fired position.
I never disassembled the bolt, and everything looks good,but I can't tell if anything is wrong. Does anyone have any ideas, or is there a website that has pictures of a correctly assembled bolt? Or is there any other common problems with the bolts?
 
Sounds like there could be an issue with the trigger. Take the trigger off and give it a good squirt with some lighter fluid. Put a white peice of paper down before doing this, you will be shocked on how much crud and crap comes out.

Did the bolt function OK before you mounted the scope?

Good advice. However, I would use a spray can of automobile Carburetor and Choke Cleaner. Lighter fluid will work, but it is very volatile. WD-40 will also work. By attaching the small tube that comes with the can, you can reach into the small places.

Trigger adjustment was mentioned. Check for broken parts, and a missing or broken sear or trigger spring. Also a worn sear / trigger will not allow engagement.

Buffdog, no I never dryfired it before mounting the scope. Will try cleaning the trigger group first,then check trigger adjustment. Thanks guys
 
buffdog,
Carburator cleaner will clean the trigger and degrease it, it works great for cleaning but leaves everything really dry. Lighter fluid will evaporate quickly and leave a light film of lube on everything that should move inside the trigger.
 
A few other things.

A) Check the action screws. Make sure the tang screw is not too tight. Loosen both action screws, then re-tighten gradually and check to see if the bolt stays cocked. The action is fairly easy to bend and the wood can be compressed enough to either missalign or bind. Try the action out of the stock to se if it works properly without any tension on the action.
Bolt should have a gap with the protrusion, into the notch like so:

If there is no gap then hold the rear piece in one hand, the middle piece in the the other, rotate so that they do align and stay cocked. Watch you don't get pinched!!


Notice how the flat part of the forward section of the bolt is about 30 degrees to the bolt handle. It should be so when reinserting the bolt into the action. It moves around very freely, and comes apart if rotated 90 degrees.

B) Check the sear cutout on the bottom of the bolt. See if there is any peening, like so:

If this is the case, best bet would to to have a machinist redo the the end so the peening is gone and you have a nice even slot all the way down to the rest of the original slot. Failing that, try to find a small milling bit and a drill press. I have done a few with a flat tipped round file.

Needless to say, never yank the bolt all to way to the back too hard. It's a target rifles, not a prop in a war movie. :)

Good luck

Yes.
Little know fact.
Some armies used to train their troops to NOT slam the bolt on their bolt actions and straight pulls all the way back. Just enough to eject the empty case or else you start to wear out sear surfaces and ejectors.
